While many security practitioners use Nmap, few understand its full power. Nmap deserves part of the blame for being too helpful. A simple command such as "nmap scanme.insecure.org" leaves Nmap to choose the scan type, timing details, target ports, output format, source ports and addresses, and more. You can even specify -iR (random input) and let Nmap choose the targets! Hiding all of these details makes Nmap easy to use, but also easy to grow complacent with. Many people never explore the literally hundreds of available options and scan techniques for more powerful scanning.
In this presentation, Nmap author Fyodor details advanced Nmap usage—from clever hacks for teaching Nmap new tricks, to new and undocumented features for bypassing firewalls, optimizing scan performance, defeating intrusion detection systems, and more.
